Sending Metrics to Mimir

Prometheus remote_write

remote_write:
  - url: http://localhost:9009/api/v1/push
    headers:
      X-Scope-OrgID: tenant1

Grafana Alloy

prometheus.remote_write "mimir" {
  endpoint {
    url = "http://mimir:9009/api/v1/push"
    headers = { "X-Scope-OrgID" = "tenant1" }
  }
}

Multi-tenancy

multitenancy_enabled: true
# All requests require: X-Scope-OrgID: <tenant-id>

Architecture

Write Path

Client → Distributor → Ingester (WAL) → Object Storage (blocks)

Read Path

Client → Query-frontend (cache/sharding) → Query-scheduler → Querier ← Store-gateway
